Pre-owned, used and refurbished Cisco PA-8B-S/T

We carry new and refurbished PA-8B-S/T ISDN port adapters for the Cisco 7200 Series routers. The PA-8B-S/T provides up to eight S/T-type BRI interfaces used to connect to an ISDN WAN through an external Network Termination 1 (NT1) device. Each PA-8B-S/T interface consists of two bearer (B) channels that can transmit and receive data at the rate of 64 kbps, full-duplex, and one data (D) channel that can transmit and receive data at the rate of 16 kbps, full-duplex. The interfaces use an RJ-45 receptacle and standard straight-through twisted-pair cable.

As an independent supplier, we can offer more equipment options than you'll find from the distributor, including new, used and refurbished PA-8B-S/T. In some instances, our pre-owned equipment may still be in new condition and still sealed in original factory packaging, but cost only a fraction of what you would pay for the same product from the distributor.

At MLCP, we guarantee any pre-owned Cisco PA-8B-S/T purchase with our comprehensive lifetime warranty. All refurbished PA-8B-S/T equipment is tested to factory specifications and transported safely to your door. Our experience as a supplier of used network hardware has taught us that we have to be better than the manufacturer, and that key principle guides us every day.

Marketing Information

The 8-Port ISDN BRI Port Adapter provide network administrators with flexible solutions that encompass a broad range of organizational networking needs, allowing them to maximize router efficiency and economy for ISDN applications. The eight-port BRI port adapter supports S/T interfaces, and used in environments where NT-1 support is not required. Port adapter offer basic "two-B-plus-D" connectivity, supporting 2 B-channels, each operating at 64 or 56 Kbps for a maximum data rate of 128 Kbps. A single D-channel is supported for signaling. BRI port adapter is particularly useful for aggregating traffic from relatively low-speed ISDN networks into high-end routers, as well as providing back-up functionality for high-speed links in the case of network failure.
